In order to evaluate the effect of planting date and different amounts of manure, chemical fertilizer and their combination on some agromorphological and essence characteristics of Moldavian Balm. A split plot experiment was conducted in a randomized complete block design with three replications at the research farm of Shahrekord University in 2018. In this experiment, the main factor was 3 levels of planting dates: 20 April, 12 May and 3 June, while 6 levels of manure application: 1) no amended fertilizer (Control) 2) 25% urea + 75% manure 3) 50% urea + 50% manure 4) 75% urea + 25% manure 5) 100% urea and 6) 100% manure, were used as subplot factors. The results showed that planting date, fertilizer and the interaction of planting date and fertilizer had a significant effect on all the characteristics studied at this experiment. So that, the maximum number of flowering branches and biological yield were derived from 3 June + 100% manure and 3 June + 50% urea + 50% manure, the maximum essential oil from 20 April and 3 June + 100% manure and the maximum essential oil yield from planting date of 3 June and 100% manure were obtained.
